When you(the male) are having intercourse doggy style and you are extremely drunk. Regergitate on the back of the female you are pounding, the trick is to not let any of the omlette(your puke) spill until you have climaxed.

Justin was so hammered last night that he puked on Alana's back, she asked "what was that," and he responded, "oh that's just the spanish omlette." She couldn't believe that he had cooked her breakfast and pigged out.
